Obama and Hickok are sixth cousins, six-times removed. Their common ancestor is Thomas Blossom, who came to Plymouth, Massachusetts in 1629 from Leiden, Holland. Obama’s 4th great-grandfather, Jacob Dunham, was 6th cousins with Wild Bill. Obama’s mother, Stanley Ann, is also a Dunham.

“The ancestry of Wild Bill Hickok was published by NEHGS some years back, which showed he descended from the Blossom family of Cape Cod, an early family written up in one of our scholarly publications,” said Child. He added, “Since we had also recently done the ancestry of Senator Obama, finding this connection was a little easier.” Click here to see the Obama – Hickok family tree – Wild Bill is related to Obama through his mother Polly Butler.
